A new bisthiazole chemosensor (3) with phenolic substituents at the position 2 of the thiazole rings was prepared. The chemosensor 3 acts as a potential dual-function fluorescence chemosensor with Cu2+ and Zn2+ ions causing complete quenching and ratiometric change of fluorescence, respectively. The mechanism of fluorescence was based on the cation-induced inhibition of excited-state intramolecular
制备了在噻唑环的2位具有酚取代基的新的联苯并唑化学传感器(3)。化学传感器3充当具有Cu 2+和Zn 2+离子的潜在双功能荧光化学传感器,分别引起荧光的完全猝灭和比例变化。荧光的机理是基于阳离子对激发态分子内质子转移(ESIPT)的抑制。
